The function of ENSG00000177103 (DSCAML1, DS cell adhesion molecule like 1) is as follows. Cell adhesion molecule that plays a role in neuronal self- avoidance (PubMed:11453658). Promotes repulsion between specific neuronal processes of either the same cell or the same subtype of cells. Promotes both isoneuronal self-avoidance for creating an orderly neurite arborization in retinal rod bipolar cells and heteroneuronal self-avoidance to maintain mosaic spacing between AII amacrine cells (By similarity). Adhesion molecule that promotes lamina-specific synaptic connections in the retina: expressed in specific subsets of interneurons and retinal ganglion cells (RGCs) and promotes synaptic connectivity via homophilic interactions (By similarity). {ECO:0000250|UniProtKB:E1C8P7, ECO:0000250|UniProtKB:Q4VA61, ECO:0000269|PubMed:11453658}.
